ESXi update guide

This guide is written with ESXi 4.1 update 1 in mind, however it will work with any update version from 3.5 onwards.

First off you will require vSphere CLI, this is a free download available to everyone with a valid VMware login. If you don’t have one you can easily register for a new one. Download from the VMware website

Power off all VM’s or vMotion them to another host and place the host in maintenance mode. (Right click on the host and select Enter Maintenance Mode)

The upgrade package contains two update bulletin parts. The esxupdate bulletin and the upgrade bulletin. These both need to be installed by running these commands on the computer with the vSphere CLI installed on it.

Ensure these commands are run from this directory C:Program FilesVMwareVMware vSphere CLIbin>
